CAsEflfENT-WINDOW HOLDER.

Application filed August 10, 1925. Serial No. 49,395.

To ZZ whom t may concern:

Be it known that l, JOHN W. BUTLER, a citizen of the United States, residing,` at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Casementllfindow Holders; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appel tains to make and use the same.

This invention relates to improvements in devices for holding easement windows in open position, and it is my object to provide a device of this character which will be ef;- ceptionally simple and inexpensive, will he efficient and desirable, and will not interfere with window screens, draperies or the like, novel provision being made for releasing the holder when the window is to be closed.

Viith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being' supplemented by the accompanying drawing.

Figure l is a horizontal sectional view through a easement window frame showing the window in elevation and illustrating the latter closed, thel improved holder being shown in operative relation with the frame of the window.

Figure 2 is a view similar to Figure 1 but illustrating` the manner in which the holder operates to retain the window in its ope-n position.

Figure 3 is a. vertical sectional view on line 3-3 of Figure 2.

Figure t .is a detail vertical sectional view on the line t-Jl of Figure 2.

ln the drawings above briefly described, F designates the frame of a. easement window, and W has reference to the window hinged in the usual manner at H.

Appropriate brackets l and 2 are provided for attachment to the frame and the window respectively, by means of screws or the like 3. Pivoted to the bracket 1, is a relatively long link 4 having one opening or a plurality of suchopenings 5 between its ends. Pivoted to the bracket 2 is a comparatively short link 6, the free ends of the two links 4r and 6 being pivoted together as indicated at 7. A lever S is fulcrumed between its ends at 9 to the lever 6, preferably at a point near the bracket 2, one end of this lever being` pivoted at 10 to a slide 11 which is mounted for movement along the link 4, said slide being provided with a downwardly project-ing stud 12 for reception in one of the openings 5, according` to the distance which it is desired to open the window W. The slide 11 is mounted. upon the link d in such a manner that said slide may move vertically to disengage the stud 12 from the opening 5, and to effect this movement of the slice, the end of the lever 8, remote from said slide, is merely pulled downwardly, the fulerum 9 being suiliciently loose to permit this downward movement of the one end of the lever, to raise the other end thereof, thus elevating the slide. 11 and moving the stud 12 clear of the opening` 5 with which it was previously engaged. Then, the window may be readily closed, during which operation, the slide 11 moves freely along the link a. lf desired, a pull chain or the like 13 may depend from the free end of the lever 8, for manipulating the latter to release the stud 12, if it is not otherwise in easy reach.

Preferably, the slide 11 is formed from a piece of sheet metal bent into the form of an inverted channel, the side walls of this channel being provided with inwardly bent stops 14 which are downwardly spaced from the link l to a suliicient extent, allowing the required upward movement of the slide 11, but serving to arrest such upward movement when the stud 12 is free of the link 4.

By employing the novel construction shown and described or a substantial equivalent thereof, a very etlicient and desirable device is produced, and on account of the existing advantages for the details disclosed, such details are preferably followed. How ever, within the scope of the invention as claimed, modifications may of course be made.

I claim:

l. A easement window holder comprising a pair of links pivoted together, means for pivoting one link to the window frame and means for pivoting the other link to the window, one of said links being provided with an opening, a slide movable freely along,V this link and mounted for vertical movement with respect to such link, said slide having :i stud projecting downwardly from its upper side for reception in said llO opening', and a. Carrying member pivoted to Said slide at one of its ends and pivoted to the other link.

Q. A structure as specified in claiml 1; seid slide comprising a piece of sheet inetal bent into inverted chzinnel-sliape, the Side walls of said slide having inwardly bent Stopg to abut the lower side of tlie slideengaged link, limiting the upward movement of said slide. 10

In testimony whereof I have hereunto affixed my signature.
